    Abd Razak NA, Abu Osman NA, Kamyab M, Wan Abas WA, Gholizadeh H
    Am J Phys Med Rehabil, 2014 May;93(5):437-44.

    This report compares wrist supination and pronation and flexion and extension movements with the common body-powered prosthesis and a new biomechatronics prosthesis with regard to patient satisfaction and problems experienced with the prosthesis. Fifteen subjects with traumatic transradial amputation who used both prosthetic systems participated in this study. Each subject completed two questionnaires to evaluate their satisfaction and problems experienced with the two prosthetic systems. Satisfaction and problems with the prosthetic's wrist movements were analyzed in terms of the following: supination and pronation; flexion and extension; appearance; sweating; wounds; pain; irritation; pistoning; smell; sound; durability; and the abilities to open a door, hold a cup, and pick up or place objects. This study revealed that the respondents were more satisfied with the biomechatronics wrist prosthesis with regard to supination and pronation, flexion and extension, pain, and the ability to open a door. However, satisfaction with the prosthesis showed no significant differences in terms of sweating, wounds, irritation, pistoning, smell, sound, and durability. The abilities to hold a cup and pick up or place an object were significantly better with the body-powered prosthesis. The results of the survey suggest that satisfaction and problems with wrist movements in persons with transradial amputation can be improved with a biomechatronics wrist prosthesis compared with the common body-powered prosthesis.

    Biomed Eng Online, 2014 Apr 23;13:49.
    PMID: 24755242 DOI: 10.1186/1475-925X-13-49
    BACKGROUND: The design and performance of a new development prosthesis system known as biomechatronics wrist prosthesis is presented in this paper. The prosthesis system was implemented by replacing the Bowden tension cable of body powered prosthesis system using two ultrasonic sensors, two servo motors and microcontroller inside the prosthesis hand for transradial user.

    METHODS: The system components and hand prototypes involve the anthropometry, CAD design and prototyping, biomechatronics engineering together with the prosthetics. The modeler construction of the system develop allows the ultrasonic sensors that are placed on the shoulder to generate the wrist movement of the prosthesis. The kinematics of wrist movement, which are the pronation/supination and flexion/extension were tested using the motion analysis and general motion of human hand were compared. The study also evaluated the require degree of detection for the input of the ultrasonic sensor to generate the wrist movements.

    RESULTS: The values collected by the vicon motion analysis for biomechatronics prosthesis system were reliable to do the common tasks in daily life. The degree of the head needed to bend to give the full input wave was about 45°-55° of rotation or about 14 cm-16 cm. The biomechatronics wrist prosthesis gave higher degree of rotation to do the daily tasks but did not achieve the maximum degree of rotation.

    CONCLUSION: The new development of using sensor and actuator in generating the wrist movements will be interesting for used list in medicine, robotics technology, rehabilitations, prosthetics and orthotics.

    Tuberculosis (TB) is the most prevalent infectious disease in Southeast Asia. It causes both pulmonary and extrapulmonary diseases. TB of the wrist is rare and presents as osteomyelitis or tenosynovitis. We report a middle-aged male with carpal bone tuberculous osteomyelitis. He presented with left wrist pain initially treated as gouty arthritis. Within 2 weeks, he developed seropurulent discharge with osteomyelitic changes on imaging. He underwent debridement, and intraoperatively, there was destruction of most carpal bones. Histopathological examination revealed chronic granulomatous inflammation with abscess formation. Anti-TB medication was initiated, and he made a complete recovery with almost full range of wrist movement after 9 months of treatment. This case serves as a reminder that TB is a great mimicker, and a high index of suspicion is required to make a diagnosis of TB of the wrist. Early initiation of anti-TB is pivotal to prevent complications and deterioration of joint functions.

    Tendon transfer for radial nerve palsy is a common procedure done under general anesthesia. We describe a surgical technique of triple tendon transfer with wide awake local anesthesia no tourniquet (WALANT). We transfer flexor carpi radialis to extensor digitorum communis, palmaris longus to extensor pollicis longus, and pronator teres to extensor carpi radialis brevis. This is commonly known as the Brand transfer. Our anesthetic or WALANT solution consists of up to 200 mL of 1:400,000 epinephrine, 0.25% lidocaine buffered with sodium bicarbonate. This technique overcomes the problem of judging the appropriate amount of transfer tension by observing awake patients actively extend their fingers, thumb, and wrist during the surgery and making adjustments before we close the wound. In our experience, there is no need of brain retraining because a patient is able to immediately use the flexor muscles to perform extension movements. WALANT is a safe and viable option for radial nerve tendon transfers.

    Malays Orthop J, 2017 Nov;11(3):45-46.
    PMID: 29326766 DOI: 10.5704/MOJ.1711.002
    A 30-year old male right handed professional tennis player complained about reduced athletic performance, chronic pain and restricted extension of his right wrist. Lateral radiograph of the right wrist demonstrated an osteophyte projecting from the dorsal lip of the lunate bone. The presence of an osteophyte on the lateral radiograph of the lunate along with the history, clinical examination, intra-operative findings, and post-operative satisfactory result made the diagnosis of dorsal luno-capitate impingement syndrome reasonable.

  7. Fulltext Intra- and Inter-observer Variability in Different Methods of Measuring Carpal Collapse
    Agrawal S, Chabra T, Pandey S, Bhardwaj P
    Malays Orthop J, 2019 Mar;13(1):20-24.
    PMID: 31001379 DOI: 10.5704/MOJ.1903.003
    Introduction: Carpal collapse of wrist occurs in disorders like rheumatoid arthritis and Kienbock's disease. Three techniques have been described to measure carpal collapse. First, the carpal height ratio (CHR), measured by dividing carpal height by 3rd metacarpal length. Second, the revised carpal height ratio (RCH ratio), measured by dividing carpal height by length of capitate. Third, capitate radius distance (CR index), measured by shortest distance between distal edge of radius and the proximal edge of capitate. The index publications describe good reliability of all these but which method out of the three is best in terms of intra- and inter-observer variability is not known. The purpose of this study was to find out which method had the least inter- and intra-observer variability for determining carpal collapse. Materials and Methods: Fifty normal wrist postero-anterior radiographs were studied by three assessors who measured CHR, RCH ratio and CR index separately. The measurements were repeated after one month by all the three observers. The results were then statistically analysed. Results: The p-value was <0.001 in all the three assessors in CR index meaning that the intra-observer variability was least in CR index. For the inter-observer variability intra class coefficient of 0.9 indicated that the CR index has the least variability. Conclusion: CR index is the most reproducible method to measure carpal collapse. The method which provides accurate measurement of carpal collapse will allow better staging of carpal disorders.

  8. Fulltext Relationship of ulna styloid fracture to the distal radio-ulnar joint stability. A clinical, functional, and radiographic outcome study
    Ajit Singh V, Jia TY, Devi Santharalinggam R, Gunasagaran J
    PLoS One, 2023;18(1):e0279210.
    PMID: 36662743 DOI: 10.1371/journal.pone.0279210
    BACKGROUND: Ulna styloid fracture occurs approximately about 55% of all distal end of radius fractures. However, the clinical and functional outcome of these fractures remains indefinite.

    RESULTS: Only 56 patients with distal radius fractures had concomitant ulna styloid fractures. The mean age was 32 years (range: 18-69; SD: ± 12.7). The majority were men. The mean time from injury was 18.7 months (range: 6-84; SD: ± 13.3). The most common was Frykman 2, followed by 6, type 8, and type 4. All were closed fractures; 60.7% were base, and 39.3% were tip fractures. 50% were treated with casting, 48.3% plating, and 1.8% external fixation. The mean period of casting was 7.67 weeks (range: 4-16; SD ± 3.1). The ulna styloid was united in 35.7%. There is no significant difference in the range of movement between those with ulna styloid union and non-union. The Ballottement test and Piano key sign was statistically insignificant between both groups. All the displacements were dorsal except in 1 case. The mean displacement of ulna styloid is 1.88mm (SD±1.08, Range: 0.20-4.60mm). The mean VAS score at rest and work is not statistically significant. The mean grip strength and functional score (DASH) are similar in both groups.

    CONCLUSION: Ulna styloid fractures do not contribute to the DRUJ instability and the status of the union of the ulna styloid and the site of the ulna styloid fracture (tip or base) did not have a bearing on the range of movement and functional status of the affected wrist. Temporary DRUJ immobilization might allow TFCC recovery.

    Simultaneous ipsilateral fractures involving radial head and distal end of radius are uncommon. We present our thoughts on which fracture should be addressed first. A 68-year-old lady sustained an ipsilateral fracture of the right radial head and distal end of radius following a fall. Clinically her right elbow was posteriorly dislocated and right wrist was deformed. Plain radiographs showed an intraarticular fracture of the distal end of radius and a comminution radial head fracture with a proximally migrated radius. Magnetic resonance imaging (MRI) showed no significant ligament injuries. We addressed her distal radius first with an anatomical locking plate followed by her radial head with a radial head replacement. Our rationale to treat the distal end radius: first was to obtain a correct alignment of Lister's tubercle and correct the distal radius height. Lister's tubercle was used to guide for the correct rotation of the radial head prosthesis. Correcting the distal end fracture radial height helped us with length selection of the radial head prosthesis and address the proximally migrated radial shaft and neck. Postoperative radiographs showed an acceptable reduction. The Cooney score was 75 at 3 months postoperatively, which was equivalent to a fair functional outcome.

    Carpal tunnel syndrome (CTS) is a hand disorder which indicates the presence of symptoms such as pain, numbness, and muscle weakness among the patient. CTS is an occupational related disorder which can occur in any profession. However, it can be prevented and managed. The aims of the research were to determine the prevalence of acquiring CTS among nurses who worked in the wards and occupational risk factors involving the upper limbs during nursing tasks performance. The specific aims were to determine the relationship between the prevalence of acquiring CTS and individual factors (age, gender, race, educational level, duration of work and medical history), relationship between the prevalence of acquiring CTS and occupational risk factors in nursing tasks. Nurses profession was chosen as they are performing multitask involving upper limbs especially the wrist joints. Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) was used to determine the level of severity in CTS. Occupational risk factors were assessed by using the Rapid Upper Limb Assessment (RULA). This research was a cross sectional mode which was carried out at a government university medical centre from November through December 2010. Eighty nurses were involved in the research. The respondents were required to fill in the socio-demographic information sheet. Those having CTS were required to fill in the BCTQ. Assessments were performed by observing of the job activity through RULA. The results showed that the prevalence for nurses acquiring CTS is 7.5%. The RULA assessment also indicated that the risk factor was in the highest level with a score of 7. No relationship was shown between the prevalence of CTS and race, gender, educational level and medical history. Significant relationship was indicated by the prevalence of CTS and occupational risk factors. In conclusion, a significant prevalence of CTS related to age of more than 30 years old, Malay races compared to Indian, working experience of more than 10 years and respondents with right hand dominant. Occupational risk factors also indicated among the active nurses. Therefore, it is important for us to modify the work environment, work flow, work methodology and ergonomic factors in order to prevent the nurses from acquiring CTS. Furthermore, education about the condition of CTS should be implemented and reinforced especially among the higher risk nurses.

    PMID: 23770863 MyJurnal
    INTRODUCTION: The distal radius is the most common fracture site in children, but local information on the fracture pattern, mechanism of injury and socio-demographic characteristics of the fracture is lacking.

    MATERIAL METHODS: We interviewed 126 children and their family members who were under follow up for this fracture in a single institution over a period of 2 years. Radiological images were reviewed to ensure that only those with fracture in the distal one third of the forearm were included.

    RESULTS: The overall incidence of this fracture increased with age, and male dominance was noted starting from schooling age. Most fractures occurred at home (38.8%), and 52.3% of all fractures were due to low energy falls. Sports injuries were mainly due to playing football, and road accidents due to riding bicycles. There were 49 (38.8%) children with incomplete fractures, and 19 (15.0%) with physeal plate fractures.

    CONCLUSION: Male dominance for distal radius fracture occurred at a comparatively younger age in our population. Preventive measures should focus on home environment since this is the most common place for fracture to occur. Special attention should be paid to boys after the school going age.

    PMID: 17600993
    We report a case of scapholunate dissociation which was initially missed and presented late. A modification of Blatt dorsal capsulodesis performed using dorsal intercarpal ligament (DICL) and extra tunnel appears not only to add to dorsal stability but also address the volar problem as well. This modification may be a better alternative to the current technique of using a single flap.

    Introduction: Carpal tunnel syndrome (CTS) is the most commonly encountered neuropathy. The entrapment of the median nerve at the wrist can be corrected with a carpal tunnel release (CTR) procedure. The objective of this retrospective study was to determine the demographic, medical, and surgical characteristics of the patients with CTS who presented for CTR surgery in a tertiary hospital in Malaysia. Materials and Methods: Malaysians patients with CTS who had undergone a CTR during the period from 1st June 2017 to 31st December 2017 were enrolled into the study. Each patient had a minimum follow-up of three months. The demographic data of age, gender, race and occupation, and the comorbid illnesses and associated risk factors were recorded. The prevalence and occurrence of CTS in the dominant or non-dominant hand and the effectiveness of surgical intervention were also noted. Data was collected, analysed and stored in Microsoft Excel and SPSS 25. Results: There was a total of 76 cases of CTR surgeries done in 62 patients in the study. Eighty percent of the patients were female, and most of the patients belonged to the age group of 41-60 years. Malays constituted 74.2% of the patients, and 34% were housewives. Hypertension, dyslipidaemia and diabetes mellitus were the three major comorbidities. Cervical spondylosis was seen in one-fourth of the patients. Bilateral hand involvement was present in 54.8% of patients. 59.7% of CTR surgery was done on the dominant hand alone, 17.7 % CTR on the non-dominant hand alone and 22.6% CTR on both hands. Numbness and pain (50%) were the predominant presenting symptoms. The most positive signs were the Durkan test (77.6%), followed by the Tinel sign at the carpal tunnel and the Phalen's test. At follow-up, three months or more, after the surgery, 75% of the patients showed a satisfactory improvement. Conclusion: Patients, who had undergone CTR, had a higher prevalence of pre-morbid conditions, and a quarter of them presented with associated cervical spondylosis. The most common presentation was a combination of numbness and pain. Many obtained satisfactory improvement post-surgery and thus open surgery could be considered a reliable treatment for CTS.

    The total replacement of wrists affected by rheumatoid arthritis (RA) has had mixed outcomes in terms of failure rates. This study was therefore conducted to analyse the biomechanics of wrist arthroplasty using recently reported implants that have shown encouraging results with the aim of providing some insights for the future development of wrist implants. A model of a healthy wrist was developed using computed tomography images from a healthy volunteer. An RA model was simulated based on all ten general characteristics of the disease. The ReMotion ™ total wrist system was then modelled to simulate total wrist arthroplasty (TWA). Finite element analysis was performed with loads simulating the static hand grip action. The results show that the RA model produced distorted patterns of stress distribution with tenfold higher contact pressure than the healthy model. For the TWA model, contact pressure was found to be approximately fivefold lower than the RA model. Compared to the healthy model, significant improvements were observed for the TWA model with minor variations in the stress distribution. In conclusion, the modelled TWA reduced contact pressure between bones but did not restore the stress distribution to the normal healthy condition.

    The wrist is the most complex joint for virtual three-dimensional simulations, and the complexity is even more pronounced when dealing with skeletal disorders of the joint such, as rheumatoid arthritis (RA). In order to analyse the biomechanical difference between healthy and diseased joints, three-dimensional models of these two wrist conditions were developed from computed tomography images. These images consist of eight carpal bones, five metacarpal bones, the distal radius and ulna. The cartilages were developed based on the shape of the available articulations and ligaments were simulated via mechanical links. The RA model was developed accurately by simulating all ten common criteria of the disease related to the wrist. Results from the finite element (FE) analyses showed that the RA model produced three times higher contact pressure at the articulations compared to the healthy model. Normal physiological load transfer also changed from predominantly through the radial side to an increased load transfer approximately 5% towards the ulnar. Based on an extensive literature search, this is the first ever reported work that simulates the pathological conditions of the rheumatoid arthritis of the wrist joint.

    Understanding the pathomechanics involved in rheumatoid arthritis (RA) of the wrist provides valuable information, which will invariably allow various therapeutic possibilities to be explored. The computational modelling of this disease permits the appropriate simulation to be conducted seamlessly. A study that underpins the fundamental concept that produces the biomechanical changes in a rheumatoid wrist was thus conducted through the use of finite element method. The RA model was constructed from computed tomography datasets, taking into account three major characteristics: synovial proliferation, cartilage destruction and ligamentous laxity. As control, a healthy wrist joint model was developed in parallel and compared. Cartilage was modelled based on the shape of the articulation while the ligaments were modelled with linear spring elements. A load-controlled analysis was performed simulating physiological hand grip loading conditions. The results demonstrated that the diseased model produced abnormal wrist extension and stress distribution as compared to the healthy wrist model. Due to the weakening of the ligaments, destruction of the cartilage and lower bone density, the altered biomechanical stresses were particularly evident at the radioscaphoid and capitolunate articulations which correlate to clinical findings. These results demonstrate the robust finding of the developed RA wrist model, which accurately predicted the pathological process.

    PMID: 28435562 DOI: 10.5704/MOJ.1607.010
    Avulsion fracture of the brachioradialis origin at its proximal attachment on the lateral supracondylar ridge of the distal humerus is exceedingly rare, and only two cases have been reported in the literature so far. In this article, we present a 38 years old patient who sustained a closed avulsion fracture of the lateral supracondylar ridge of left humerus at the proximal attachment of brachioradialis following a fall backwards on outstretched hand after being struck by a lorry from behind while riding on a two-wheeler (motorcycle). He was managed with above elbow plaster for four weeks followed by elbow and wrist mobilization. At final followup, the patient had painless full range elbow motion with good elbow flexion strength. The unique mechanism by which this avulasion fracture occurred is explained on the basis of the mode of injury, position of the limb and structure and function of the brachioradialis muscle.
